FRUIT-JAR.

SPECIFICATION forming part of Letters Patent No. 342,384,6(31266. May25, 1886,

Application tiled September 29, 1585 Serial No. 178,597. (No model.)

To aZZ whom it may concern:

Be it known that l, P. KENNEDY REEvEs, ofRridgeton, county ofOumberland,and State of New Jersey, haveinvented new and usefulImprovements in Fruit Jars, and I do hereby declare that the followingis a full and exact description of the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

This invention relates, generally, to that class of fruit-jars which hasfor its distinguishing characteristic a jar having holdingribs withinclined bearing-surfaces on its neck, and a yoke having depending armsturned inwardly to engage with the ribs on thejar, which yoke isadapted, when partially rotated on the cover of the jar, to clamp thecover tightly to thejar, and specially to that subdivision of this classwhich has for its distinguishing characteristic a vented cover andproper means for closing the vent; and it consists in the combination,with the yoke and vented cover, ofa pivoted spring-arm adapted. to swinginto place to close the vent, as will be fully described hereinafter.

In the drawings, Figure 1 represents a partial view of the improved jar;Fig. 2, a top view of the same, and Fig. 3 apartial sectional view ofthe invention.

To enable others skilled in the art to make my improved jar, I willproceed to describe fully the construction of the same.

A represents thejar, having on its neck the usual holding-ribs, a a,with inclined bearingsurfaces on the lower side of the same, as shown inFig. 1.

B, Figs. 1 and 3, represents a rubber ring resting upon a propershoulder of the jar, in the manner well understood.

0 represents a glass cover constructed generally in the usual well-knownmanner, but essentially provided with a central stud, c, Fig. 8,projecting above the upper face of the cap, which stud is provided witha vent-opening extending through it, as shown.

D represents a yoke constructed generally like others of its class, butessentially provided with a central opening, through which the stud c ofthe cover projects, as shown in Fig. 3.

d d represent arms depending from the main portion of the yoke, whichare provided with inwardlyturned flanges adapted to engage with the ribsa c on the neck of the jar, as shown in Fig. 3.

E represents a spring-arm having a bearing-plate, 0, adapted, when inits normal position, to close the vent, but capable of yield ing underpressure, to give the proper vent when necessity requires it. Thisspring-arm is pivoted to one side of the yoke in such manner as to becapable of a swinging movement to one side, as shown in dotted line,Fig. 2, when it is desired to uncover the vent.

The bearingplate for closing the vent is a caplike projection, e, formedin the arm itself. The niannerof using this improved jarclosure does notdiffer in its general features from the manner of using others of thisclass. The vent in this case is left open, as is usual during theboiling action, by swinging the spring-plate to one side, as shown inFig. 2. YVhen the proper time, however, has arrived for closing thevent, the spring-arm is simply turned upon its pivot into the properposition.

Some of the advantages of the described construction are as follows:There are but two pieces in the cover portion of the jar, and these,being comparatively large, cannot be readily lost. hen the jar is beingused in the cooking of the fruit, all the parts are in place, andconsequently when the cooking operation is completed it is not necessaryto apply any additional parts to the hot and steamingjar, but, on thecontrary, simply to move a part already in place into a differentposition. By means of the inclined sides of the stud of the cover therotating spring-arm E is readily moved into and out of its closingposition.

The spring-arm bears on the vent with sufficient pressure to prevent theingress of air, but is elastic enough to allow the egress of gasescaused by imperfect processing, in which case it forms a perfectsafety-val ve by preventing the bursting of thejar.

Opening the valve facilitates the removal of the glass lid, theatmospheric pressure being relieved as soon as the air enters.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is I 1. In combination with the yokeand vented I 5 cover, the pivoted spring-arm, substantially asdescribed. f \Vitncsses:
